You upload your track somewhere, play it back next to a commercial release, and yours sounds small. Quieter. Less finished.
Nine times out of ten, the culprit is loudness normalization — and it hits AI-generated music especially hard.
What −14 LUFS actually is
LUFS (Loudness Units relative to Full Scale) is how streaming platforms measure the perceived loudness of a whole track — not the peaks, the overall energy a listener experiences.
Most major streaming services normalize playback to around −14 LUFS. If your track is louder than that, they turn it down. If it's quieter, some platforms turn it up, others just leave it quiet.
The consequence: you can't win by being loud. A track slammed to −8 LUFS gets turned down to −14 and ends up sounding *more* squashed than a track mastered to −14 in the first place — all the dynamics you crushed to get loud, gone for nothing.
Why AI exports are all over the map
Generators don't master. Depending on the tool, the model, and the prompt, your export might come out at −20 LUFS (whisper quiet), −9 (slammed), or anywhere between — and two generations from the same prompt can land in different places.
That means every AI track needs the same two-step treatment a studio release gets:
- Measure what the file actually is
- Move it to the standard without wrecking the dynamics
What Release Ready does
Release Ready is Cambrian's mastering pipeline. Under the hood it runs a two-pass EBU R128 loudness normalization: the first pass measures your track's real loudness characteristics, the second applies a correction targeting −14 LUFS with true-peak limiting — so the file lands where streaming platforms expect, with headroom against clipping on lossy encodes.
Alongside the loudness work, one run also:
- Exports a clean WAV (44.1 kHz / 16-bit) and a distribution-grade MP3 with your metadata embedded
- Validates your title, artist, and cover art against store expectations (3000×3000 artwork spec)
- Handles the AI disclosure so the release states plainly how it was made
The output is a package a distributor will accept — and after the run, you get a handoff guide for services like DistroKid, RouteNote, and Amuse if you're taking the track wider than Cambrian.
What it costs
Mastering runs on credits. The Creator plan ($5.99/mo) includes 3 masters a month; Pro ($12.99/mo) includes 10. If you need extras, one-time packs are $9 for 1, $24 for 3, or $69 for 10 — and purchased credits don't expire.
Your credit is only spent when a job actually runs. Failed jobs release the credit back.
The honest version
Mastering isn't magic and −14 LUFS isn't a sound — it's a target that stops the platform from mangling your track on playback. What it buys you is a level playing field: your release sits at the same perceived loudness as everything else, and gets judged on the music.
If the track's good, that's all you need.
